DETAILED DESCRIPTION OF THE INVENTION

To better clarify the purposes, technical solutions and advantages of the embodiments of the invention, the technical solutions of the embodiments of the invention will be clearly and completely described. Obviously, the embodiments in the following description are merely illustrative ones, and are not all possible ones of the invention. All other embodiments obtained by those ordinarily skilled in the art based on the following ones without creative labor should also fall within the protection scope of the invention.

The invention abandons the architectural design, in the prior art, that multiple applications share one base system environment and dependency, and designs an application platform using a new system architecture. Each application container instance in the application platform of packages an application, an application connector interface, a user data interface and an exclusive base system environment and dependency for running the application, so that all applications are mutually independent, and even if one application container instance is attacked, only the attacked application container instance will be destroyed, and other application container instances can run normally without being affected. The application container instance refers to an entity unit for carrying the application and the base system environment and dependency for running the application, and may be a container formed based on a Linux namespaces isolation technique represented by Docker, or an individual physical host or virtual machine

As shown in FIG. 2 , the invention provides an application platform, comprising a user interface 201, an application container connector 203, at least one application container instance 205, and a user data set 200.

The user interface 201 is used for realizing direct interaction with users to transmit an interactive operation performed by the users through the user interface 201 to the application container connector 203 and obtaining feedback, matching the reactive operation, from the application container connector 203. Specifically, the user interface is a human-computer interaction interface similar to the operation interface of the Windows system, and allows users to perform operations to execute computer instructions such as starting an application.

The application container connector 203, as a bridge between the user interface 201 and the application container instance 205, accesses the application container instance 205 according to the interactive operation performed by the users through the user interface 201 (such as requesting for access to a link) and feeds contents, presented by the application container instance 205, back to the user interface 201, as a response to the interactive operation performed by the users through the user interface 201.

The application container instance 205, as shown in FIG. 3 , comprises an application 205-3, an application connector interface 205-1 connected to the application container connector 203, a user data interface 205-7 connected to the user data set 200, and a base system environment and dependency 205-5 for running the application 205-3; the base system environment and dependency 205-5 is a basic environment and dependency exclusive to the application 205-3 and just needs to meet usage requirements of this application (a most simplified edition meeting the usage requirements of this application). For example, as for the Windows operation system, a DirectX module needs to be installed to run some games, a Chinese language package needs to be installed in a Chinese environment, a Chinese input method is needed for Chinese input, and if a notebook application in an English edition is used, none of the DirectX module, the Chinese language package and the Chinese input method is needed. In this way, the application container instance 205 will not occupy too much space; and the base system environment and dependency for the application does not need to be upgraded under the condition that the application is not upgraded, thus guaranteeing the stability of the application container instance and solving the problem that, in the prior art, a common base system environment and dependency has to be upgraded to adapt to all applications with the increase of the applications (different applications have different requirements for the base system environment and dependency) and becomes over-complicated.

After being started (the application runs automatically after the application container instance is started), the application container instance 205 receives an access from the application container connector 203 through the application connector interface 205-1, accesses user data corresponding to the application through the user data interface 207-7, and then feeds the presented contents back to the application container connector 203. The application container instance 205 may be started through the following methods: first, the application container instance 205 is started instantly after being configured by an application platform administrator, and at this moment, the application container connector 203 can directly access the application container instance 205; second, after being configured, the application container instance 205 is started according to a received start request signal (the start request signal is from the application container connector 203 or the application platform administrator), at this moment, the corresponding application container instance 205 is accessible, and then the application container connector 203 accesses the application container instance.

The user data set 200 is used for storing user data to be accessed by the application container instance 205. To better protect user data, the user data in the user data set 200 may be designed into multiple pieces of mutually independent user data by those skilled in the art, and the user data can be accessed merely by corresponding application container instances 205. That is, different application container instances can only process corresponding user data, so even if user data corresponding to one application container instance is destroyed, user data corresponding to other application container instances will not be affected, thus solving the problem that, in the prior art, data destruction and leakage may be caused because user data can be operated by all applications.

As a preferred solution of this embodiment,

The application container connector 203 is also used for transmitting the interactive operation performed by the users through the user interface 201 to the application container instance 205, and the application container instance 205 is also used for applying the interactive operation, transmitted from the application container connector 203, to the application 205-3.

As another preferred solution of this embodiment, the application platform further comprises:

An application container template library 208 storing at least one application container template;

The application container manager 207 is configured to receive a request from the application container connector 203 (such as a request for starting an application) and establish an application container instance using a corresponding application container template. Specifically, the application container manager 207 selects a corresponding application container template from the application container template library 209 according to a request from the application container connector 203, generates a corresponding application container instance according to the selected application container template (in this embodiment, the relationship between application container templates and application container instances is similar to the relationship between Docker images and Docker containers in a Docker application container engine), and starts and configures the application container instance. The at least one application container instance is configured by the application platform administrator, or is established by the application container manager 207.

The application container manager 207 is also configured to delete a corresponding application container instance according to a received application container instance removal request (for example, a user performs an operation through the user interface, and the application container connector sends an application container instance removal request to the application container manager according to the operation; or, the application platform administrator sends an application container instance removal request to the application container manager when monitoring that one application has not been operated for a long time), that is, the corresponding application container instance will be destroyed after being used by users, so that application residue is avoided, and self-restoration is realized, for example, if an application container instance is destroyed by an attack, the application container manager will delete this application container instance according to an application container instance removal request, and a new application container instance, that is not attacked or destroyed, will be established at next startup.

In this preferred solution, the application container connector 203 is also used for requesting the application container manager 207 to start a corresponding application container instance according to the interactive operation performed by the users through the user interface 201, and accessing the application container instance after the corresponding application container instance is accessible. After receiving the request, the application container manager 207 establishes the application container instance through the method mentioned above.

For the sake of a good understanding, the actual application process of the application platform of the invention will be explained by way of example:

A user performs an operation through the user interface 201 to request to start an application (such as Google Chrome, WPS or Photoshop); for example, the user double clicks a shortcut of Photoshop on the user interface to request to start the application Photoshop;

The application container connector 203 accesses an application container instance according to the interactive operation performed by the user through the user interface 201 (the application container instance is configured by the application platform administrator or is established by the application container manager, and is started according to a request from the application container connector); in this example, the application container instance comprises the application Photoshop, an application connector interface connected to the application container connector, a user data interface connected to the user data set, and a base system environment and dependency for running the application Photoshop; after being started, the application container instance 205 receives an access from the application container connector 203 through the application connector interface 205-1, accesses user data corresponding to the application through the user data interface 205-7, and then feeds, presented contents, back to the application container connector 203; and the application container connector 203 feeds the contents, presented by the application container instance 205, back to the user interface 201, as a response to the request for starting an application container instance initiated by the user through the user interface 201.

In a case where an application container instance corresponding to the application requested to be started by the user is neither configured by the application platform administrator nor established by the application container manager 207, the application container connector 203 requests the application container manager 207 to start a corresponding application container instance according to the interactive operation performed by the user through the user interface 201. For example, the application container connector 203 checks, according to the interactive operation performed by the user through the user interface 201, whether the application platform has configured the application container instance corresponding to the application requested to be started by the user; if not, the application container connector 203 requests the application container manager 207 to start the corresponding application container instance;

The application container manager 207 receives the request from the application container connector 203, selects a corresponding application container template from the application container template library 209, generates a corresponding application container instance according to the selected application container template, and starts and configures the application container instance, and the application container manager 207 transmits information, indicating that the application container instance has been started and configured, to the application container connector 203;

When receiving the information indicating that the application container instance has been started and configured, the application container connector 203 accesses the application container instance;

The application container instance 205 receives an access from the application container connector 203 through the application connector interface 205-1, accesses user data corresponding to the application through the user data interface 205-7, and then feeds presented contents back to the application container connector 203, and the application container connector 203 feeds the contents, presented by the application container instance, back to the user interface 201, as a response to the request for starting an application container instance initiated by the user through the user interface 201.

The invention further provides another application platform, comprising a user interface 201, an application container connector 203, an application container manager 207, and a user data set 200.

The user interface 201 is used for realizing direct interaction with users to transmit an interactive operation performed by the users through the user interface 201 to the application container connector 203 and obtaining feedback, matching the interactive operation, from the application container connector 203. Specifically, the user interface is a human-computer interaction interface similar to the operation interface of the Windows system, and allows users to perform operations to execute computer instructions such as starting an application.

On one hand, the application container connector 203 requests the application container manager 207 to start a corresponding application container instance according to the interactive operation performed by the user through the user interface 201 (for example, the users request for starting an application or accessing a link) and accesses the application container instance after the corresponding application container instance is assessable; and on the other hand, the application container connector 203 feeds contents, presented by the application container instance 205, back to the user interface 201, as a response to the request for starting an application container instance initiated by the user through the user interface.

The application container manager 207 is configured to receive the request from the application container connector 203 (such as a request for starting an application) and establish an application container instance using a corresponding application container template. Specifically, the application container manager 207 selects a corresponding application container template from an application container template library 209 according to the request from the application container connector 203 and generates a corresponding application container instance according to the selected application container template (in this embodiment, the relationship between application container templates and application container instances is similar to the relationship between Docker images and Docker containers in a Docker application container engine), and starts and configures the application container instance.

As shown in FIG. 3 , the application container instance 205 comprises an application 205-3, an application connector interface 205-1 connected to the application container connector 203, a user data interface 205-7 connected to the user data set 200, and a base system environment and dependency for running the application 205-3; the base system environment and dependency 205-5 is a basic environment and dependency exclusive to the application 205-3 and just needs to meet usage requirements of this application (a most simplified edition meeting the usage requirements of this application). For example, as for the Windows operation system, a DirectX module needs to be installed to run some games, a Chinese language package needs to be installed in a Chinese environment, a Chinese input method is needed for Chinese input, and if a notebook application in an English edition is used, none of the DirectX module, the Chinese language package and the Chinese input method is needed. In this way, the application container instance 205 will not occupy too much space; and the base system environment and dependency for the application does not need to be upgraded under the condition that the application is not upgraded, thus guaranteeing the stability of the application container instance and solving the problem that, in the prior art, a common base system environment and dependency has to be upgraded to adapt to all applications with the increase of the applications (different applications have different requirements for the base system environment and dependency) and becomes over-complicated. After being started (the application run automatically after the application container instance is started), the application container instance 205 receives an access from the application container connector 203 through the application connector interface 205-1, accesses user data corresponding to the application through the user data interface 205-7, and then feed presented contents back to the application container connector 203.

The user data set 200 is used for storing user data to be accessed by the application container instance 205. To better protect user data, the user data in the user data set 200 may be designed into multiple pieces of independent user data by those skilled in the art, and the user data can be accessed merely by corresponding application container instances 205. That is, different application container instances can only process corresponding user data, so even if user data corresponding to one application container instance is destroyed, user data corresponding to other application container instances will not be affected, thus solving the problem that, in the prior art, data destruction and leakage may be caused because user data can be operated by all applications.

As a preferred solution of this embodiment,

The application container connector 203 is also used for transmitting the interactive operation performed by the users through the user interface 201 to the application container instance 205, and the application container instance 205 is also used for applying the interactive operation, transmitted from the application container connector 203, to the application 205-3.

As another preferred solution of this embodiment, application container manager 207 is also configured to delete a corresponding application container instance according to a received application container instance removal request (for example, a user performs an operation through the user interface, and the application container connector sends an application container instance removal request to the application container manager according to the operation; or, an application platform administrator sends an application container instance removal request to the application container manager when monitoring that one application has not been operated for a long time), that is, the corresponding application container instance will be destroyed after being used by users, so that application residue is avoided, and self-restoration is realized, for example, if an application container instance is destroyed by an attack, the application container manager will delete this application container instance according to an application container instance removal request, and a new application container instance, that is not attacked or destroyed, will be established at next startup.

For the sake of a good understanding, the actual application process of the application platform of the invention will be explained by way of example:

A user performs an operation through the user interface 201 to request to start an application (such as Google Chrome, WPS or Photoshop); for example, the user double clicks a shortcut of Google Chrome on the user interface to request to start the application Google Chrome;

The application container connector 203 requests the application container manager 207 to start a corresponding application container instance 205 according to the interactive operation performed by the user through the user interface 201;

The application container manager 207 receives the request from the application container connector 203, selects a corresponding application container template from the application container template, generates a corresponding application container instance according to the selected application container template, and starts and configures the application container instance. In this example, the application container instance comprises the application Google Chrome, an application connector interface connected to the application container connector, a user data interface connected to the user data set, and a base system environment and dependency for running the application Google Chrome; after the application container instance 205 is started, the application container manager 207 sends information, indicating that the application container instance has been started and configured, to the application container connector 203;

The application container connector 203 accesses the application container instance after receiving the information indicating that the application container instance has been started and configured;

The application container instance 205 receives an access from the application container connector 203 through the application connector interface 205-1, accesses user data corresponding to the application through the user data interface 205-7, and then feeds presented contents back to the application container connector 203;

The application container connector 203 feeds the contents, presented by the application container instance 205, back to the user interface 201, as a response to the request for starting an application container instance initiated by the user through the user interface 201.

The invention further provides an application management method applied to an application container manager 207, comprising:

A request for starting an application container instance from an application container connector 203, such as a request for starting an application or a request for accessing a link (essentially a request for starting an explorer application) is received; and

An application container instance is generated using a corresponding application container template; specifically, the application container manager 207 selects a corresponding application container template from an application container template library 209 according to the request from the application container connector 203, generates a corresponding application container instance according to the selected application container template, (in this embodiment, the relationship between application container templates and application container instances is similar to the relationship between Docker images and Docker containers in a Docker application container engine), and starts and configures the application container instance;

Wherein, the application container instance 205 comprises:

An application 205-3;

An application connector interface 205-1 connected to the application container connector 203 to feed contents, presented by the application 205-3, back to a user interface 201 through the application container connector 203;

A base system environment and dependency 205-5 for running the application.

As a preferred solution of this embodiment, the method further comprises:

A corresponding application container instance is deleted according to a received application container instance removal request (for example, an application platform administrator sends an application container instance removal request to the application container manager when monitoring that one application container instance has not been used for a long time), that is, the corresponding application container instance will be destroyed after being used by users, so application residue is avoided, and self-restoration is realized, for example, if an application container instance is destroyed by an attack, the application container manager will delete this application container instance according to an application container instance removal request, and a new application container instance, that is not attacked or destroyed, will be established at next startup.

The examples in the above implementations are used to assist in further understanding the solutions of the invention rather than limiting the technical solutions of the invention. Although the invention has been described in detail with reference to the above embodiments, those ordinarily skilled in the art would appreciate that amendments to the technical solutions of the above embodiments or equivalent substitutions to part of the technical features in the above embodiments can be made without making the essence of corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the invention.
